IATA Operational Safety Audit (IOSA)

​The IATA Operational Safety Audit (IOSA) Program is an internationally recognized and accepted evaluation system designed to assess the operational management and control systems of an airline. The IOSA audit creates a standard that is comparable on a world-wide basis, enabling and maximizing the joint use of audit reports. This has saved the industry over 6400 redundant audits and continues to lead to extensive cost-savings for IOSA participating airlines.

All IATA members are IOSA registered and must remain registered to maintain IATA membership. See who is already on the IOSA Registry.

As the COVID-19 outbreak is affecting the world, IATA is working to ensure the IOSA Program continues to meet industry needs.Measures have been taken to assist airlines that are affected by this crisis. For this purpose, a program option called ‘Extenuating Circumstances for Audit Conduct’ was made available, as well as the upcoming IOSA Support Program. IATA will continue working and making adjustments as it becomes necessary.Relevant documents, such as Operator Alerts and Temporary Revisions to the IOSA manuals have been released and are available in our documentation site.

Single engine aircraft operations

Single pilot aircraft operations

Helicopter operations

Seaplane operations

During an audit, ISARPs are applied only to those aircraft that are of the type authorized in the Air Operator Certificate (AOC) and utilized in commercial passenger and/or cargo operations. Other owned or leased aircraft that are not of the type authorized in the AOC and/or not utilized in commercial air transport operations, will not be evaluated during an audit as they are considered outside the scope of IOSA. However, the existence of such aircraft will be referenced with an explanation in the IOSA Audit Report.
